We are developing a functionality that allows the users to save the downloaded file. We are struggling to get a popup where the user can select a target location / folder to save his file. Can this be achieved using rails?

How do I allow client to download browser plugin/activeX control? Can you suggest the way to do it?

When we make ActiveXControl and then use it in website as JavaScript object. This JavaScript object can call functions written in ActiveXControl like xmlhttprequest plugin has send() method in its plugin. When Client Browses it asks to download that plugin. In case you allow then browser downloads it and install it for you. Similarly your plugin will be installed, but plugins are mostly not recommended as most users hesitate to download that untill and unless it is something from sites which user trust.
